Next time, on a hot day, if you happen to stop under the shade of a big tree, just look up and see: does the tree enjoy its own shade? The sun is blazing down mercilessly on the tree, which is absorbing the heat and giving us shade. Does it charge us parking fee for standing under it? Does it ask for sympathy or help when the summer makes shed its leaves? Does it get angry with the world when white ants eat away its inner core, or pollution covers it with layers of dust?
The tree has life. It is just that we do not understand it, ignorance is not excuse. The same way, ignorance of the feelings of people around us is no excuse. There are many humans who give us shade, shall we thank them in some small way?
